More than one colour. To tell you more than one thing.

Know you’re safe

Nest Protect constantly monitors its sensors and batteries. A quick green glow when you turn off the lights says that everything's working.

A light in the dark

Most of the time, the light is off. If you need a glass of water in the middle of the night, Nest Protect will quietly glow white to light your way.

An early warning

If there's only a little smoke, like you've just burned toast, it will glow yellow and give you a friendly Heads-Up so you can check on things.

In an emergency

When smoke or carbon monoxide reaches dangerous levels, Nest Protect sounds the alarm, pulses red and tells you where the emergency is.

Works with your Nest Learning Thermostat and Nest Cam

If Nest Protect sounds the alarm, it tells your Nest Thermostat to turn off the boiler – the most common source of carbon monoxide leaks. Your Nest Cam will also record a clip while the alarm is going off so that you can see what happened.

Nest Protect has been tested to comply with safety standards UL 2034, UL 217, and NFPA-72 set out by UL and California State Fire Marshal.
